I have tested the solution. It works as expected, thank you! You are the best!
Hello, no trouble at all. Thank you for the help!
I edited the file tablepress-shortcode-filter-get-parameter.php
$filter_term = preg_replace( ‘#[^a-z0-9 &;]#i’, ”, $filter_term );
I then tested the get parameter URL with parameters like
https://example.net/test/?table_filter=1&&b
https://example.net/test/?table_filter=1&&b
It appears that only the string before the symbols are accepted, and the && and anything following is completely disregarded.
Thank you!
